Ultra Trimmer

Best Trimming Machine: The Ultra Trimmer

The biggest knock on industrial trimmers has always been that they destroy the gland heads containing the essential oils we’re after. The units from Ultra Trimmer simulate scissors and avoid manhandling precious flowers while preserving the trichomes. The company’s even been giving live demonstrations with microscopes at our Cannabis Cups for over five years to show how gently the machines work. It’s no secret why Ultra Trimmers are the first products to be federally patented specifically for trimming cannabis.

Under Current Evolution 9XL

Best Hydroponic System: Under Current Evolution 9XL from Current Culture H2O

Explosive hydroponic growth rates result when plant roots have access to highly oxygenated nutrient solution. The patented Sub-Current Culture system in the UCE9XL utilizes premium pumps to recirculate a supercharged fluid rich with dissolved oxygen for previously unattainable levels of absorption.

Advanced Nutrients

Best Wetting Agent: Wet Betty from Advanced Nutrients

The plant scientists at Advanced Nutrients understand that when plant-food solution sits on top of hard soil, roots can’t properly absorb the vital liquid and food. Wet Betty, a non-ionic surfactant, lessens surface tension while softening and enhancing water droplets for better uptake, leading to stronger growth and bigger harvests. Great as a soil drench or foliar feed, Wet Betty helps your nutes permeate more efficiently and effectively to maximize yields.
